Hi there, Does anyone have a fail2ban filter for OpenSMTPD?
I would like to block the many many AUTH LOGIN attempts as you can see here from the logs: Jun 17 11:55:49 gw smtpd[594]: 7eeebcc95623efe1 smtp event=failed-command command="AUTH LOGIN" result="503 5.5.1 Invalid command: Command not supported" Jun 17 11:55:52 gw smtpd[594]: 7eeebcc95623efe1 smtp event=closed reason="io-error: Connection reset by peer" Cheers, M.
